FAQs on 3 Days Timetable: Units & Measurements (2025) - Physics for JEE Main & Advanced
| 1. What are the fundamental forces in nature? |  |
| 2. What is the difference between accuracy and precision of instruments? | |
Ans. Accuracy refers to how close a measured value is to the true value, while precision refers to the consistency or reproducibility of repeated measurements. An instrument can be precise but not accurate if it consistently gives measurements that are far from the true value. An instrument can be accurate but not precise if it gives measurements that are consistently close to the true value but vary significantly from each other.
| 3. What are the sources of errors in measurement? | |
Ans. There are several sources of errors in measurement, including systematic errors and random errors. Systematic errors are caused by flaws in the measuring instrument or technique and can lead to consistent deviations from the true value. Random errors are caused by unpredictable variations in the measurement process and can lead to fluctuations in the measured values. Other sources of errors include environmental conditions, human errors, and limitations of the measuring instrument.
| 4. How does a Vernier caliper work? | |
Ans. A Vernier caliper is a measuring instrument used to measure the length, diameter, or thickness of an object with high accuracy. It consists of a main scale and a sliding Vernier scale. The main scale is marked in millimeters, while the Vernier scale has smaller divisions that allow for more precise measurements. When taking a measurement, the user aligns the object between the jaws of the caliper and reads the measurement from the main scale and the Vernier scale. The Vernier scale provides an additional decimal place of accuracy.
| 5. What is dimensional analysis and how is it useful in physics? | |
Ans. Dimensional analysis is a method used in physics to check the correctness of equations and formulas, and to derive relationships between physical quantities. It involves the analysis of the dimensions (such as length, time, mass, etc.) of the quantities involved in an equation. By checking that the dimensions on both sides of an equation are consistent, one can verify the correctness of the equation. Dimensional analysis is also useful in converting between different units and in solving problems involving scaling and proportionality.
